Unconjugated bilirubin alleviates experimental ulcerative colitis by regulating intestinal barrier function and immune inflammation

Figure 4 UCB increased expression of tight junction proteins in the colon and decreased intestinal permeability. A: Protein expression of tight junction occludin (n = 3); B: D-Lactate level in serum (n = 5). Data are expressed as means ± SEM. ^cP < 0.001 vs control group, and ^fP < 0.001 vs DSS group. UCB: Unconjugated bilirubin; DSS: Dextran sodium sulfate; SEM: Standard error of the mean.
